Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0070] Before explaining and describing the embodiments of the present invention in detail, the application scenarios of the embodiments of the present invention are firstly introduced.

[0071] In security monitoring and other fields, in order to protect the privacy of users, it is usually necessary to perform privacy masking processing on a partial area of ​​the monitoring image. For example, for the collected surveillance video, it is necessary to perform privacy masking in each video frame of the surveillance video where there are faces, car windows, license plates, etc. that will leak user privacy. Play according to the user's permission. For example, for users with private viewing rights such as the police, the original video im...

Abstract

The invention discloses a privacy masking processing method and device, belonging to the field of image processing. The method includes: determining a target area where a target to be occluded may exist from an image and a confidence level of the target area, and the confidence level of the target area is used to indicate the probability that a target to be occluded may exist in the target area; determining based on the confidence level of the target area Privacy masking processing parameters of the target area; based on the privacy masking processing parameters of the target area, privacy masking processing is performed on the target area. The invention realizes the variable-intensity privacy masking process on the target area according to the confidence degree of the target area, and improves the flexibility and accuracy of the privacy masking process.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and in particular, to a privacy masking processing method and device. Background technique [0002] As the public pays more and more attention to privacy protection, the application of privacy masking in the field of image processing is becoming more and more extensive. Privacy masking refers to the method of masking or blurring the area where people or vehicles in the image are waiting to be masked in order to protect personal privacy. It is mainly used in video surveillance images. [0003] In the related art, a privacy masking processing method is provided, which includes: using computer vision and other intelligent means to detect the object to be masked in the image to detect the area where the object to be masked exists, and then unify the detected area privacy masking treatment. [0004] However, in practical applications, due to the limitation of detection capabilit...
